摘要:
(Z)-1-[2-(tri-o-tolylstannyl)vinyl]-1-cyclohexanol (1) was synthesized by the additive reaction of 1-Ethynylcyclohexanol with tri-o-tolyltin hydride. One or two of the o-tolyl groups of compound (1) was substituted by Cl, Br, I to yield derivatives of the type CH2(CH2)(4)CH(OH)CH=CHSn(o-tol)(3-n)X-n [n = 1, X = Cl (2), Br (3), I (4); n = 2, X = Br (5)]. The compounds (1 - 5) characterized by elemental analysis, H-1 NMR and FT-IR Spectroscopy. The crystal structures of (1) and (4) have been determined by single crystal X-ray diffraction analysis. The Sn atom in (1) exhibits tetrahedral geometry distorted towards trigonal bipyramid due to a weak intramolecular interaction between Sn and the hydroxyl O atoms [2.764(5) Angstrom], while the Sn atom in (4) adopts a trigonal bipyramidal geometry with a significant Sn(1) <-- O interaction [2.571(4) Angstrom].
